Just a few hours of watery sky on Saturday night when I was trying to find an asteroid occultation field . Failed to ID the field at the time so ended up with an 8 x 40 binocular sweep. Had a shock when a bright telescopic meteor shot across the 8 degree field at a rate of knots. I went in the 'toy box' today (kit store) and dug out an 18 mm image intensifier to sort out some lens spacings for an II set up. The intention is to use a 28 mm (or even a 20 mm) M42 lens on to the II and then use a C mount lens on to a Watec 902A camera . Tried an Ernitec 8 mm f 1.3 today and may have to drop to 6 mm to get a wide enough field. These units do not like daylight when powered up ! It would seem that further north in Scotland there have been some reasonable clear skies over the last few weeks !
Hi, A beautiful clear night last night. Captured a decent number of meteors (32). A couple of sub mag zero's and a couple very close to the moon. The ones close to the moon would have been impossible with emulsion photography and probably impossible with visual observing. Also shot a few hundred frames with the DSLR before the moon came up but nothing captured. Looking good again for tonight at this location. Cheers, Bill.
Further to your emails last week, I spent hours on Friday and Saturday night trying to get 720X576 res. The Hauppage worked fine except it produces double stars, another peculiar effect! and no matter what I did the VCAP 302 will only give 720x480. I'll need to do more thinking about this...
PS I also tried a dual camera with my older watec 120. The dual disk idea seems to work fine with some proviso's. The pc handled everything fine at low res.
However going to high res produced a few "stutters" and if the camera's try to record the same event then sometimes it works and sometimes it doesn't. (out of curiosity, as I had a feeling this might cause some problems I mounted the cameras parallel). I can't definitively say why but I thinks it's got something to do with the timings of the video clips.
So I would say that it will handle two cameras without difficulty provided they are pointing far enough apart so as not to overlap. This way the time stamps are fine.
Hi, I came across a video card on amazon called a Video Mate C100. At £11 I decided to take a gamble and buy one. It seems to work fine! I have it running at 720x576 as I type on the Watec 120/12mm/300lpm grating. So we'll see how it goes over night as the Orionids pick up. The 902 is running also on the laptop but I have given up with the full PAL on that. I used to be able to run 720x480 but another wretched "update" and it won't entertain that now. So it seems happy at 640x480 for the moment. Hopefully the clear skies will continue for tonight and tomorrow night. Since my last clear spell I've had nearly 90mm of rain. Yuk. cheers, Bill.
